    • The invention relates to a nitride light emitting device including first and second conductivity type nitride layers and a plurality of active regions emitting light of different wavelength. The active regions are sequentially formed between the first and the second conductivity type nitride layers. The active regions include at least one first active region having a plurality of first quantum barrier layers and quantum well layers, and a second active region emitting light of a wavelength larger than that of the first active region. The second active region has a plurality of second quantum barrier layers and at least one discontinuous quantum well structure formed between the plurality of second quantum barrier layers. The discontinuous quantum well structure comprises a plurality of quantum dots or crystallites.

    • Disclosed herein is a nitride semiconductor light emitting device, which comprises plural active layers emitting light of different wavelengths. The device comprises p-type and n-type nitride layers, and a plurality of active layers sequentially stacked between the p-type and n-type nitride layers to emit light having different wavelengths. The active layers comprise at least a first active layer to emit a first wavelength light, and a second active layer to emit a second wavelength light, of which wavelength is longer than that of the first wavelength light. Both the first and second active layers are composed of at least one quantum well layer and a quantum barrier layer alternately arranged, and the first active layer is disposed closer to the p-type nitride layer than the second active layer. The number of quantum well layers of the first active layer is less than that of the second active layer.
